Latest Patents
One of Hayakawa's latest patents is a screw type vacuum pump with introduced inert gas. This innovative design features a pump casing with a suction inlet and a discharge outlet, incorporating a pair of rotors that mesh and rotate in synchronization. The vacuum pump effectively evacuates a reaction vessel to achieve a predetermined negative pressure condition. By introducing inert gas into the compression working chamber, the design not only generates heat to warm the rotors and casing wall but also reduces the partial pressure of the process gas, preventing side reaction products from accumulating.
Another significant patent is the vacuum evacuation system, which combines a non-positive displacement type vacuum pump, known as a molecular pump, with an oil-free positive displacement type vacuum pump, referred to as a screw vacuum pump. This configuration ensures high pumping speed in a high vacuum range while preventing oil contamination in the evacuated system.
